Application filed August 13, 1917. Serial No. 185,897.

To all whom z 't-mag concern:

Be it known that I, ARTHUR E. 020m", a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Garcass Dehairing and Cleaning Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accentpanying drawings, and totlie numerals of reference marked thereon, which form a part of this specification.

' This invention relates to improvements in carcass dehairing and cleaning machines;

It is an object of this invention to provide a machine of the class s ecified in which the carcasses are continuous y advanced'over a stationary inc-lined support and in which the scraping mechanism act upwardly through the support to continuously rotate, dehair and clean the carcasses while theyare being positively advanced.

it is further an object of this invention to provide a hog scraper in which thecan casses are supported on a stationary slotted support and mechanisms for acting on the carcasses through the support to thoroughly dehair and cleanthe same.

It is further an object of this invention to provide a stationary supportingmecha' nism for carcasses and movable conveying mechanism, and; a scraping mechanism acti'ng upwardly on the'carc'asses from below and acting through the support and conveyer. V t

' It is further an object of this invention tojprovide an inclined stationary support extending into the scalding vat and 1a mechanism for engaging carcasses and advanc-- ing them over the stationary support intoposition to be operated upon'by ascraping 'nechanism positioned beneath the support and conveyer.

It is further an object of this invention to provide a hog scraping machine in which the scra 'aing mechanisms act upwardly against the gravity of the carcasses and in which the surface of the carcasses: presented" to the scraping mechanisms is in! substantially the same plane thereby overcoming the objection that difierent parts of the carcasses are treated'to a different extent.

"It is farther an object of this inventionto: pro vi 1 hog scraping niacliincdn; which the carcasses are so supported and the scraping mechanism so disposed that all parts o f'the carcasses are acted upon with equal force and etficiency tothoroughly clean. thesame. I

It is, further an object of this invention toprovide a machine of the class specified in which the refuse falls by gravity from the machineand is conveyed to one side of the machine and in which means are provided for continuously spraying the carcasses with hot water to wash the hair and refuse therefrom and from the machine. Other and further important objects of this invention will be apparent from the disclosures in the specification, and drawings.

The invention- (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

0n the drawings:

V v I The pairs: of bars forming the platform are spaced;

tank 41.

the vat, and aredirected substantially horizontal at their ends and rest on a supporting block 12.

J ournaled in suitable bearings on the scalding vat 6, and frame, are shafts 13--14, on which are secured sprocket wheels 1516, about which are trained sprocket chains 1718, to which are rigidly secured angle irons 19. As shown in Fig. 4, the upper run of the chain runs on angle iron tracks 20, and the lower lap of the chains run in channel iron tracks 21. l v

Rig-idly secured to' the transverse bars,

lags or angle irons 19, are a plurality ofv pushing blades or members 22, which travel in the'space provided between each pair of platform bars 7, as shown clearly in Fig. 4.

Suitable tension devices -17 -17 are provided for maintaining the tension of the conveyor chains. Journaled in the frame beneath the supporting platform are a plurality of scraping shafts 23, 24, 25, 26 and 27, on each of which are secured drums 28, to which are secured flexible arms 29,

' of belting or other suitable material on the outer ends of which are secured scraping blades 30. The scraping arms are of such Width as to fit between the pairs of platform bars 7, as shown clearly inFigs. 4 and 5.

Each of said scraping shafts 23'to 27,

inclusive, have a sprocket wheel 31, thereon, and idler sprockets 32, 33 and'34, are provided, of which the idler. sprockets 32 and 33, are journaled to the frame between the respective pairs of scraping shafts 24-25, and 2627. A. .sprocket'chain 35,

is trained around said sprocket wheels and a suitable 'automatictension device 1s'pro-' vided for tightening thechain which comprises a sprocket wheel 36, and weight 37, movable in suitable guides or ways 38. secured on the shaft 23, is a loose and a tight pulley 39- 40, to receive a driving belt' from' operated from the shaft 23, by means of a sprocket chain 49, trained around pulleys 5 051, secured on shaft 23, and a stud shaft 52, and a pinion 53, on said shaft 52, meshes with a gear 54, on the shaft 45.

' For the purpose of driving the conveyer slowly, a drive shaft 55, is Journaled in the top of the frame, provided with a tight and loose pulley 5657 on one end, and,

a. pinion 58, on its opposite end which meshes with a large gear 59, on a s'haft60,-

around and around a sprocket wheel 63,

on conveyer shaft'14. p

For the purpose of spraying and washing'the carcasses, a pump 644, communicates with the tank 41, and communicates with I suitable pipes 65, by means of a pipe .66.

Spray pipes or heads 67, are secured to the:

pipes 65, andproject through the upperpar tition or wall 68, into position to deliver a spray or shower of water continuously upon the carcasses. For the purpose of driving the pump, a belt 69, is trained around friction pulleys 70, on. shaft 23, and friction pulley 71, on pump shaft The operation is as follows: I,

The carcasses are'delivered into the scalding vat 6, and when properly treated are pushed onto the horizontal extension ofthe stationary platform or support 7, from whence they are elevated and advanced by the pushing members or blades 22, over the scraping mechanism. As the carcasses are being advanced, the scrapers are acting thereon through the support and conveyer blades to thoroughly dehair, clean, and polish the carcasses, and at the same time the spraying mechanism'is delivering a spray to wash the hair andrefuse from thev carcasses and scraping mechanism ontothe conveyer 48, which conveys the hair and refuse outside of the machine and, deposits the same into a-pile for further removal.

Inasmuch as the carcasses are supported and operated upon'from below, it is obvious that allparts ofthe carcasses are equidistant from the scrapers, thiat'is, the shout and face and; all other parts, ,owingtof the gravity of the carcasses, is in the same plane with the body and the scrapers acting upwardly through the supportand'coin veyer onthe carcasses against the gravity of the carcasses, thoroughly cleanses: all

parts of the carcasses uniformly and 'efliclently. Also, the scraping mechanism serves to continuously rotate the carcasses .while scraping the same, thereby presenting all parts of the carcassto the scraping action to thoroughly same. s 4 e I am aware that'many changes in the construction may be made and details may be varied through a wide range, and I there fore do not desire to limit myself otherwise than necessitated by the prior art.

I claim as my inventionz. r I Y dehair and clean the 1. In a machine of the class 'specifiech stationary means for supporting carcasses,
